`String` | `getExtensionFromMimeType(String mimeType)` Return the registered extension for the given MIME type.
`static String` | `getFileExtensionFromUrl(String url)` Returns the file extension or an empty string if there is no extension.
`String` | `getMimeTypeFromExtension(String extension)` Return the MIME type for the given extension.
`static MimeTypeMap` | `getSingleton()` Get the singleton instance of MimeTypeMap.
`boolean` | `hasExtension(String extension)` Return `true` if the given extension has a registered MIME type.
`boolean` | `hasMimeType(String mimeType)` Return `true` if the given MIME type has an entry in the map.

### Inherited methods
From class `java.lang.Object`
`Object` | `clone()` Creates and returns a copy of this object.
`boolean` | `equals(Object obj)` Indicates whether some other object is "equal to" this one.

`final void` | `notifyAll()` Wakes up all threads that are waiting on this object's monitor.
`String` | `toString()` Returns a string representation of the object.
`final void` | `wait(long timeout, int nanos)` Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object, or some other thread interrupts the current thread, or a certain amount of real time has elapsed.
`final void` | `wait(long timeout)` Causes the current thread to wait until either another thread invokes the `notify()` method or the `notifyAll()` method for this object, or a specified amount of time has elapsed.

### getSingleton

    public static MimeTypeMap getSingleton ()

Get the singleton instance of MimeTypeMap.

Returns
`MimeTypeMap` | The singleton instance of the MIME-type map.

### hasExtension

    public boolean hasExtension (String extension)

Return `true` if the given extension has a registered MIME type.

Parameters
`extension` | `String`: A file extension without the leading '.'

Returns
`boolean` | `true` if there is an extension entry in the map.

### hasMimeType
